S LAG-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 484,659, dated October 18, 1 892,

Application tiled July 30, 1889. Serial No, 319.232. (No model.)

T0 a/ZZ whom it may concern;

Be it known that I, JOHN F. KEIPER, of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Separators; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which 1t appertains to make and use the invention.

This invention relates to separators.

The object of the invention is to produce a device by which the separation of the various minerals contained in lead ore may be achieved in a ready and eiiicient manner, particularly of lead containing gold, silver, or other preciousmineral from slag, matte, or other waste products.

With these objects in view the invention resides, essentially, in a separator provided with two outlet-discharge openings, one for the passage of the lead and the other for the passage or discharge of the waste material.

Furthermore, the invention resides in a separator having adjustable pieces in the leaddischarge, whereby the levelof the discharge may be regulated.

Furthermore, the invention resides in a sepator having a detachable coverprovided with means whereby the same may be extended in order to make connection with the furnace more convenient; and, finally, the invention resides in noveldetails of construction wherebyt-he operativeness of the device is insured in a ready, convenient, and economical manner.

I have illustrated the invention in the accompanying drawings, in which- Figure l represents a sectional View of a separator made in accordance with my invention, showing it connected to a furnace. Fig. 2 is a view in section taken at right angles to that of Fig. 1. Fig. 3 is a plan view of the separator with the cover in position, and Fig. 4 is a detail view of the extensible cover.

In the drawings, A represents the cover, which is provided with lugs or projections 0L, by which it may be connected to the separatorD; but any other convenient means of attachment may be used, and I do not wish to be understood as limiting myself in this respect.

a is a handle secured to the cover, whereby it may be raised from the separator. The cover is also provided with feathers or projections a2 on the sides, designed to project into a corresponding groove on the adjustable piece B, whereby the same may not be raised out of position, and with a suitable seat for the reception of the tap-jacket O and grooves 0.3 in the seat.

B represents the adjustable piece, designed to be attached to the coverA, and is provided with a groove h on each side to engage the feathers or projections a2 on the cover A.

O represents the tap-jacket, which is provided with a tap-hole c, through which the light slag or matte discharges; and it is also provided with keys c', designed to enter the grooves d3 in the cover A.

D represents the main portion otthe separator, into which the mixture of lead and slag is introduced from the furnace through the opening d. The heavy lead will descend to the bottom of the separator and be forced up through the pipe CZ and out through the spout or opening d2 into suitable coolers or through a suitable trough d'1 into molds. Cooling-pipes (Z3, through which cold water is circulated for the purposes of preventing the separatoranditsadjuncts from becoming overheated, may be introduced throughout the separator and its cover.

The outlet-pipe is provided near the spout or opening cl2 with a groove, in which may be inserted piece E for regulating the level of the lead-discharge,sai'd piece having a discharge-opening E The lighter ingredientssuch as slag or matte-will remain on top and flow out of the separator by the tap-hole c in the tap-jacket O.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a separator, the main portion having- IOO opening, and the lower ontlowpipe, the end ot which is below the level -of the 'wasteopeningr, substantially as described.

3. In a separator, the main body portion, the removable cover having secured in its end the detachable piece containing the waste? opening, and the lower outflow-pipe, the end of which is below the level of the Waste-opening, having secured therein the adjustable piece for limiting the outflow of metal, sub stantially as descr ibed.

4. In a separator, the main body portion, the removable cover having secured in its forward end the detachable piece containing the waste-opening, the lower outflow-pipe, the end of which is below the level of the Waste-opening, having secured therein the adjustable piece for limiting the outflow of' metal, and the spirallyarranged cooling-pipes in the cover and body portion, substantially as described.

5. In a separator, the cover having a removable piece at its rear end for connecting it to the furnace and a detachable piece at its forward end having a waste-opening therein, and the body portion having the outflowpipe connected therewith at its lower end, substantially as described.

6. In a separator, the main body portion, therernovablecover having secured in its forward end the detachable piece havinga Wasteopening therein, the removable piece at its rear end for connecting it with the furnace, the body portion having the outflow-pipe connected therewith at its lower end, in the end of which pipe is secured the adjustable piece for limiting the outflow of metal, and lthe spirally-arranged cooling-pipes in the cover and body portion of the separator, substantially as described.

In testimony whereof Iaiix mysgnature in presence of two witnesses.

JOHN F. KEIPER.
